Through Hole Resistors

The CMF5599K000BEEA is a through-hole, current-sense resistor. It has a thin film technology construction that allows it to have an exceptionally low resistance value at a very low cost. This type of resistor finds many uses in current sensing applications, and the CMF5599K000BEEA is no different.

Application Field

The CMF5599K000BEEA is designed for use in applications such as motor control circuits, precision instrumentation, and light switching systems. It can also be used as a voltage divider element in low-voltage circuits for signal conditioning. Its low resistance value makes it an ideal choice for precision current measurements.

The CMF5599K000BEEA is typically used in power supplies, motor controls, medical and industrial instrumentation, and various types of automotive and switching systems. It is available in two different versions – the 3W and the 5W – and also in a range of different sizes. The 3W version is available in sizes from 0402 to 2525, while the 5W version is available in sizes from 0402 to 4553.

Working Principle

The CMF5599K000BEEA is essentially a metal-oxide-varistor (MOV) attachment, which is technically termed a current-sensing element. As the name implies, it works by sensing the current flowing in the circuit and providing an output voltage proportional to it. It works by connecting the MOV to a voltage source and the multiple thin-film layers are designed to detect changes in the current flowing through the MOV.

The MOV is typically connected to a voltage divider circuit, where the voltage drop across the MOV is proportional to the current passing through it. This voltage drop is then used to measure the current passing through the resistor. The CMF5599K000BEEA also includes a temperature coefficient, which can be adjusted to compensate for temperature differences between devices.

The CMF5599K000BEEA is also used for current-limiting applications, since it is capable of handling higher current levels than other types of resistors. In this application, the resistor must be sized correctly for the specific application; otherwise, it may not be able to handle the current levels that are needed.

Advantages and Disadvantages

The main advantage of the CMF5599K000BEEA is its low cost and high accuracy. It also has a wide range of sizes to choose from, making it suitable for different applications. In addition, its thin film construction also makes it robust and reliable.

On the other hand, the CMF5599K000BEEA is not suitable for use in high reliability or safety-critical applications, since it has limited current handling capabilities. It also has a limited temperature range, making it unsuitable for use in high temperature applications.

Conclusion

The CMF5599K000BEEA is an ideal choice for current sensing and current limiting applications, due to its low cost, high accuracy and wide range of size options. Its thin film construction also makes it highly reliable and robust, making it suitable for most applications. Although it has some limitations, such as its limited current and temperature handling capabilities, overall it is a great choice for many applications.
